Aha! That's why I never use the new posts button.
It has never defined "newer than what?".

Heck, you made it easier to raise & lower, now make an alignment brace.

You know what, Mark? I think I still have 4 brand new 3/4" Thompson linear bearings around here somewhere.

I used bronze flanged bushing material. I have to keep it oiled for it to move correctly. If I don't the whole brace tries to move up or down when I raise/lower the headstock.

But it keeps aligned within 0.001. I've even used it & forgot to tighten the clamp nuts on the back of the headstock.

Rod, I have several chromed 3/4 inch shafts that came from weight lifting machines. The weights traveled up and down them on plastic bushings. Shafts seem pretty hard, but I have no idea what material they are. If you want, I'll toss one in the Twinkie Hotel for you next time I head for Texas.

Thank you, Gene.
I have the remains of a "thing" I dug out of a dumpster behind a print shop 10 or 12 years ago that may be serviceable. I think it was some kind of a laminating machine.
The particular part was a traveling beam carriage. If I remember correctly the chrome on the bar was still mostly good with some damage on one end or maybe I'm imagining that.

It is buried behind a pile of other treasures & resources out in my garage.
I'll dig it out some day soon & inspect it.
Right now I actually have to go to work for 2 or 3 or 4 hours.

Default Wiring

I've drug my feet about posting the wiring details mostly because I have way too many pictures to sort through.
You're all probably going to think this is a tedious presentation of a bunch of crap you don't need to know but that's all right. If you're bored, well what the hell? Nobody's going to make you read it anyway.

I've noticed that Mildred gets quite a few visits from lurkers overseas as well as closer to home so I'm partly going through all this for their amusement too.
Besides that, the amount of threads and replies here has dropped to less than half of what it was just 2-3 years ago so I may as well take up some of the slack.

1. I think I mentioned that I had a couple of old switches that I bought from an antique store some time ago.
This one is a 2 pole, single throw 10amp @ 125volt. I like it because it makes a satisfying "clunk" when you snap it and more because of the big ball end on the lever.
Then it has that large chrome dome and a 3/4" barrel around the lever.
The stamp identifies the makes as "A-H&H USA"; I have no idea who that is or was. Do you?

This will be my "safety"switch & I'll get back to it later.

2. I liked this DPDT switch because of the long threaded stem. I don't recall ever seeing another one quite like it but this one was a natural choice because of the box it goes in. You can see a little red dot on one side of the threads & there is another one on the other side of the stem that doesn't show in the picture.
Those red dots are actually screw holes that mount the box to the back of the controller box so the long stem allows this switch to fit under the screws, allowing me to reuse this little box.
I believe I paid $2 apiece for these switches.

3. The long neck switch replaces the little green handled one shown in this picture. It originally controlled a little cooling fan which I no longer need since I upgraded Mildred's table drive motor in 2010 or '11.

4. And here is long-neck wired in the box, ready to install to the back of the 90volt controller box.
The wires from the drive go to the 2 center taps and the output is then selected by this switch to power either Mildred's table drive motor or the head lift motor.

5. Finally, here is the long-neck selector switch installed in it's little box and mounted to the back of the 90v controller box.
The longer pair of white wires on the left go to the other side of the mill to the new head lift motor, by way of the "safety" switch which I will deal with shortly.

Right now I have to take a break to go out back & play squeaky ball with Wilson since the temperature has finally dropped from 107° to 101° and we have some shade.

The build is going good!! Of course the people overseas are interested in the Mildred based modifications, cutting edge technology is cutting edge technology, no matter where is from.

I'm constantly on my guard to safeguard the secrets of the Franken-Mill and the Franken-Drill, even the loyal readers of SFT, are not fully aware of all of the features and/or the upgrades or major modifications that are in the pipeline. Marsupial Holdings, LTD., is doing it best to keep ahead of the curve and to be a leader not a follower in the machine tool arms race. I'm even weary of our so called friends and neighbors to the north, the Canadians, they are just too polite and easy going, it makes me suspicious (or at least nervous).

Back to the subject at hand, a few questions

1 - any concern about a chain guard??
2 - any ideas about the tramming issues??
3 - any thoughts on the one-shot system??
4 - How far from Lubbock is Abilene?? (I suppose to be in Abilene in August or September, for a training class)

Well now, how about that?
It is an interesting switch. First little toggle switch I've ever had that requires such a large bore.

The long-necker intrigues me too; I've tried imagining how the compound levers or something would be arranged to trip the contacts.
